GRADUATED MOLD-CAI AUXILIARY AND MOVABLE LINER.

To all whom it may concern:

Be it known that we, LAWRENCE HURLEY and CHARLES A. BREWTON, citizens ofthe United States, residing at Washington, in

the District of Columbia, have invented new and useful Improvements inGraduated Mold-Gap Auxiliary and Movable Liners, of which'the followingis a specification.

This invent-ion relatesto type bar or slug casting machines, and' hasfor its object to provide an inexpensive, efiicient and durable meansfor adjusting the length of the mold. The drawings illustrate its aplication particularly to the well known Iergcnthaler 5 linotype machinenow in general use in printing offices in this country.

It is an important object of the invention to provide such adjustingmeans adapted to be lised with the several forms of mold now in use onthe Mergenthalermachines, with- ,out requiring structural modificationsthereof, and without changes in their operation .or manipulation.

, In theMergent-haler machine, the slug, or

' linotype is cast in a disk-like mold wheel having a mold thereinopening on both sides of the disk and disposed at right angles to aradius of the axis of the wheel. Improvements have been made in manydifferent Ways to accomplish adjustment of the slot to form slugs ofvarious lengths and thick-' nesses.- These have included central linersadjustable in length and adapted to be engaged in the mold to limit itslength; molds,

the sides of which are movable relatively,

riliners sliding longitudinally in the mold slot, and sets of blockliners adapted to be secured at one end of the mold each of a lengthnecessary to limit the, slot to the size 40 of a respective standardsized slug. As

combining accuracy in producing slugs of proper size, simplicity ofadjustment, simplicity and economy in manufacture, and a 1 f, minimumdepreciation inefficiency through i {1 wear, it has been found desirableby the makers of the Mergenthaler machine to use a mold comprisingrelatively movable cap and bottom plates carried by the mold wheel, andsolid liners of various lengths and thicknesses. This construction isfollowed at this date, and will be familiar'to those versed in the art.Owing to the large number of liners required under this system to formthe various lengths of slugs usually 5 required in printing ofiices, acomplete Speeiflcation of Letters Patent.

equipment thereof costs several hundred dollars, as they cost one dollaror more each.

It is therefore an aim of this invention to provide a single linerelement of simple form adapted to be used in conjunction with the usual'end liners, or to be substituted for one of the latter, to be clampedbetween the mold plates in the-customary manner employed with thespecial length liners, to form slugs of any desired standarddength; andwhich may be manufactured at a cost but little in excess of that of asingle one of the liners now customarily employed. This device may betermed a movable liner.

It is an end of the invention to obviate 70 the necessity for specialmechanism or special tools in changing the mold to vary the slug length.r

' A further object is to form a slug with ribs so spaced as to provide asufiicient'numher even on the shortest slug, to insure the properalinement of the slug when locked in the form. It is the case with slugsfrom the molds generally used, on which these ribs are widely spaced,that when a short slug is formed a considerable part at one end is leftwithout a rib, and locked with adjacent slugs the end without a rib islikely to be forced out (of line, a fault overcome under our method. a

Another object is to utilize the rib-form-. ing grooves of the mold toperform the function of retaining the movable liner in its variouspositions. a As it is undesirable to have the ribs on a slug formed atintervals less than one pica, and as it is often necessary to cast aline measured in units of half a pic a or nonpareil-it is a furtherobject to so form the movable liner that while being positivelypositioned by engagement with the pica spaced rib grooves, it may beutilized to alternately form slugs terminating at or intermediately ofthe pica unit intervals.

Prior liners, adjustable in length, have: 100 usually involved theobjectionable feature that when lengthened interstices are formed, intowhich the molten metaluis admitted, clogging the liner .parts andinvolving labor in cleaning before a change may be made. 10 It is anadvantage of our invention that such objection is overcome by theinoorporation of movable means within the boundary of a liner ofconstant dimensions to control its position at slight intervals wherebyIt is a valuable feature of the inventionthat by so spacing the grooves,and forming a slug may the movable liner so as to cooperate there'-with, the operator will have a positive indication in the mold itself oftherproper point at which to dispose the limiting device-the movablelinen-without the use of a rule or other measuring appliance separatefrom the mold and similarly, the length of be be readily determined, bythe number of ribs thereon, and the amount of material, if any,projecting beyond the last rib at one end, the other end rib being flushwith the end of the slug. The generally adopted scale of linemeasurement is graduated in units of picas and half-pleas, or nonpareil.

Other objects parent from the from the'drawings, in which,

There is shown in Fig. 1 a bottom mold plate 1.0 and. a cap platell'ofsubstantially the usual form, and adapted to be pngaged in theusual form of mold wheel in the customary manner. The mold face 12 ofthe bottom plate is smooth and accurately planed, while the mold face 13of the cap plate is provided with amultiplicity of transverse grooves 16which may be shape inany desirable transverse form, bu't which as shownare approximately V shaped and have equally inclined sides 15. {Themaxi.-

mum width of the grooves at the front'of the mold is a-scantone-sixteenth of aninch and they are tapered to sligthly less than thisat their inner ends. if desired, the bottom plate may be provided withthe regular guide pins 17 at each end,-adapted toengage in a mortiserecess of' the end liners 18 and 19, which in addition have ribs 20conforming to and engaged snugly 16. The liners 18 and 19 form the endsof the mold space or slot 21, and allow the formation. of' the maximumlength of slug. They are clamped bottom plates as herebolts 22enshortened, We use d mg the base member 23, corresponding 1n base hasalso a back lines by the use of our devicew To limit the size of themold constructed in accordance with our invention to an extent of threepicas or less, the bolts22 may be loosened, theleft end liner removedand a movable liner to of grooves to hold it at the desired distancefrom the opposite end liner. I The left haul liner is preferably moved,and the right hand liner left undisturbed, to form the slug in properposition for ejection by the devices customarily employed. If themold isto be shortened more than three picas the left end liner should beallowed to remain in place while the movable liner is adjusted inwardlythereof, for when the movable liner is intermediately located in themold some of the passages through which the metal has access to themold, from the present pumping devices will then be located outwardly ofthe movable liner and a waste of metal would ensue if the end liner werenot in place. between the left hand liner and the movable liner isclosed by the left hand jaw of the matrix vise, which abut-s snuglyagainst the front of the mold slot when a cast ismade, and is ofsufficient size.

varied as desired and the stem portion opens on the front face 28 of theliner body 23. It will be observed that the slot 25 is completelyisolated from the mold face 24,

I the back face 24 and the outer side face 24", whereby access of typemetal to the recess is prevented.

. Disposed in the slot 25-there is a differential plate 30 conforming tothe outline of the slot, but differing in size laterally in onedirection-transversely of the stem. The stem 31 of the plate is narrowerthan the stem of the slot, and the arms 32 of the plate are shorter thanthe slot branches 27, although fitting snugly therein transversel of thearms. .The dlli'erence in size is suci as to allow reciprocation of thedifferential plate for a distance :of half a plea. A rib 33,-conformingin shape'to the grooves 16, is formed at the outer edge of the stem 31,and similar ribs 34 are formed on the arms 32, in alinement with eachother and spaced laterally from the rib 33 one pica. The ribs projectabove the face ofthe base member 23', so that when the joker is insertedin the mold slot, the ribs 33 and 34 engage adjacent grooves 16 and holdthe movable liner with its mold side in proper parallelism with thegrooves. It will be seen that when the device is thus en aged and thebase member-23 is'pressed outwardly against the differential plate, theslug will be cast in full pica measurement, while if the base be forcedinwardly until checked by the differential plate, the amount of playbeing half a pica, the slug will be formed ofa length measurable inunits of no'npareil or half picas. This is of ,esp'ecial advantage innewspaper work, where the standard column is thirteen picas wide, and itis frequently necessary to divide the column, producing lines. of sixand one-half picas. The two stages "of adjustment are shown in Figs. 4and 5. ,Many similar situations are involved in casting smaller orlarger lines. It is "of/course understood that the clampingmeansfengaging the cap plate is loosened when themovable liner is to beadjusted; and tightened again to hold the liner iriposition. I By therecess be ing opened on"tlie front face of the mold the operator may seeat a glance how the dili'erential member set in the base To adapt thedevice to use upon the common form ofll/Iergenthaler molds already inuse, wehave =provided' the mold cap auxiliary' plate 35 illustrated inFigs. 2,.and 3, which comprises a pl'gite substantially rect angnlar inform, and of the same dimension Kin-plan as the mold cap plate on itslower 'fa'ce, being mortised ateach end to receive the alining or guidepins 17 at each end of the bottom plate. It is provided on one side withtransverse grooves-J6 similar to those 16 before described, and in useis positioned over the regular right and left endliners 37 and 38 withthe grooves on'the lower side, the cap plate 11 being then clampedthereover, after which the movable liner may be adjusted thereinwhenever desired. It will be understood of course that the 'roportionsof the parts'as illustrated may be changed and means utilized to securethe auxiliary cap plate to the regular ca plate more firmly, as may befound desira 1e.

In the useof the resent solid liners of special length for eac length ofslug age is frequently done by operators failing to make the necessarychange in the ejector device to accommodate it to the narrow slugs, anda too wide ejector coming against the special liner, either one or theother is damn ed. Such liability is obviated by the men? the movableliner described, as this may be readily forced out by the ejector,without damage. 7

A special thickness of base member 23 of the movable liner will berequired for each font of type, or each different thickness of slug tobe cast, but the same diiferential late may be used upon all the basesasmay 0 understood by forming the slots of the same depth in all. The formof the slot or plate 30 is immaterial as lon as the necessary play ofhalf a pica is al owed between the base and differential plate What isclaimed is: 1. In a device of the class described, the combination witha mold having opposed sides and an end forming means, and having spacedgrooves on one side opening on the ed e of the mold, of a. movable lineradapted to engage snugly between the grooved side and the op osite sideof the mold, and comprising a ase member'having a recess in one side tolie adjacent the grooved mold side, lying in the recess and having a.rib portion projecting above the base member for engagementwith thegrooves, said differential plate being narrower than the recess in adirection transverse to the rib, and being reci rocable in thatdirection relatively to the ase member.
